问题描述：
what is the matter with 与..what happened to
( )surprise us a lot that the student doesn't even know ( )the difference between the two words lies.
A what ;where
B It ,where
C It ,what
麻烦帮说说 A和C怎么错也帮我说说
答
It 形式主语,
where 引导状语从句
答
It 指代that从句
用where 是因为the two words lies，lie的地方，所以是where
答
it在这里做形式主语,代指that后面的事情.第二个空where是做地点状语,由于lie后边缺少介词,故用where代还in which.what不可以用在此,建议你多看一下语法书中关于从句的分析
